If I recall correctly, the GCAN dividends were distributed to UNGS share holders at a rate of 1 per 4000 UNGS shares. (someone please correct me if I am wrong here).
If the UNGS share holder paid the lowest possible price at the time for UNGS shares of .0001/share, and assuming the UNGS shares are now worthless, then each GCAN dividend cost a UNGS share holder 40 cents.
